Earlier, Addressing an election rally in Bihar's Araria district, Dr Singh said: " The Centre is giving so much money to Bihar, yet no work happens here. It is unfortunate to know that the state government is taking credit for the schemes of the Central government and their benefits are not reaching those intended."

"Since 2004, till now, the Centre has given Rs 6000 crores and for 36 districts the Centre is giving special assistance. These funds could have changed the face of the state... power, roads, education could have been given to the needy but the government has not fulfilled its duties".

The six-phase polls for 243 seats begins from October 21 and concludes on November 20.
